Vacuum oil quenching furnace is mainly used for bright quenching and annealing of alloy steel, tool steel, die steel, high speed steel, bearing steel, spring steel, stainless steel and other products. It can be divided into two types: double chamber furnace and three chamber furnace. The double-c...
Die steel contains more alloying elements, and elements with higher vapor pressure (such as AL, Mn, Mn, Cr, Si, Pb, Zn, CU, etc.) tend to evaporate when heated in vacuum, so the vacuum degree of quenching heating should be controlled properly. To prevent the volatilization of alloy elements, espe...
To reduce or avoid the evaporation of alloying elements, pressure can be increased by filling the vacuum heating chamber with high-purity neutral or inert gas (such as nitrogen, argon, helium, etc.). The pressure inside the vacuum chamber is adjusted within a range of 0.1 to 650 Pa. This vacuum p...
Vacuum protection atmosphere heat treatment method–recharge gas selection：
When using the partial pressure of heating vacuum heat treatment back filling gas should choose the high-purity neutral or inert gas, hydrogen, helium, nitrogen, argon and other common gases. Four kinds of gas cooling spe...
AISI4140 is equivalent to China’s 42CrMo steel.
42CrMo steel belongs to ultra high strength steel, with high strength and toughness, high hardenability, no obvious temper brittleness, high fatigue limit after quenching and tempering, multiple impact resistance, good low temperature impact toughne...
“Tail vacuum” (tubular vacuum) is a traditional process technology and uses “pressure sealing technology”, but it is a pity that this kind of technical measure cannot guarantee the sealing microscopically. In general, there is a tail welding that requires welding three bottoms: inner bottom, mid...

Low pressure gas protection reduces metal element evaporation
To reduce or avoid the evaporation of alloying elements, pressure can be increased by filling the vacuum heating chamber with high-purity neutral or inert gas (such as nitrogen, argon, helium, etc.).
